Abstract
One embodiment of the present specification provides a method for performing a random access procedure for coverage enhancement. The method can comprise the steps of: determining a PRACH resource for a random access preamble on the basis of a repetition level; generating a random access preamble in a specific cell; and repetitively transmitting the generated random access preamble according to the repetition level on the basis of the determined PRACH resource.
Claims5
A method for performing a random access procedure, the method performed by a Machine Type Communication (MTC) device being located in a coverage enhancement region and the method comprising:
- determining a Physical Random Access Channel (PRACH) resource for a random access preamble according to a first period, a second period, and an offset,
- wherein the first period corresponds to a period between transmission periods available for the random access preamble,
- wherein the second period corresponds to a period between start timings of the random access preamble within the transmission periods,
- wherein the offset corresponds to an offset dependent on the first period and/or the second period,
- wherein the first period, the second period, and the offset are independently configured in accordance with a repetition level, and
- wherein the first period, the second period, and the offset are configured in the MTC device through a higher layer signal sent from a base station;
- generating the random access preamble toward a specific cell;
- and
- repeatedly transmitting the generated random access preamble in accordance with the repetition level within the determined PRACH resource.
A machine type communication (MTC) device for performing a random access procedure in a coverage enhancement region, the MTC device comprising:
- a transceiver configured to transmit a random access preamble toward a specific cell;
- and
- a processor configured to determine a Physical Random Access Channel (PRACH) resource for the random access preamble according to a first period, a second period, and an offset, and control the transceiver so as to repeatedly transmit the random access preamble in accordance with a repetition level within the determined PRACH resource,
- wherein the first period corresponds to a period between transmission periods available for the random access preamble,
- wherein the second period corresponds to a period between start timings of the random access preamble within the transmission periods,
- wherein the offset corresponds to an offset dependent on the first period and/or the second period,
- wherein the first period, the second period, and the offset are independently configured in accordance with the repetition level, and
- wherein the first period, the second period, and the offset are configured in the MTC device through a higher layer signal sent from a base station.
